Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The combination of protons and neutrons is equal to the
A
atomic number
B
atomic mass
C
electrons
D
overall charge
Explanation: 

Detailed explanation-1: -Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Detailed explanation-2: -The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Detailed explanation-3: -Protons and neutrons are collectively called as nucleons.

Detailed explanation-4: -The total number of protons and neutrons in the nucleus of an atom is called its mass number.

Detailed explanation-5: -The total weight of an atom is called the atomic weight. It is approximately equal to the number of protons and neutrons, with a little extra added by the electrons.
